Whippable composition

ABSTRACT

A whippable topping composition having improved low temperature performance is prepared utilizing a mixture containing at least two emulsifiers, a primary and a secondary emulsifier. The primary emulsifier is a lactylated glycerol ester, and the secondary emulsifier is a partial or complete ester of a common food acid and a mono and/or diglyceride of a saturated or unsaturated fat forming C12 - C22 fatty acid.

Compositions adapted for the preparation of whipped toppings have now been known for a number of years and such compositions are generally in the form of dried emulsions which are conventionally prepared by drying emulsions of fat and edible water-soluble components, for example by spray-drying or freezedrying, to provide a powdered, freeflowing fat composition. When these dried emulsions are employed in the preparation of whipped toppings it is desirable that the resulting product is characterized by a high degree of over-run, acceptable viscosity and mouth-feel and freedom from chum-out of the fat.

Conventional ingredients for the dried emulsions include fat, protein, carbohydrate and an emulsifier. Examples of whippable compositions are those described and claimed in British Pat. Specification Nos. 11 13462, 1140937, 1091270, and 1019147.

One of the disadvantages of prior whippable compositions as typified by those disclosed in the abovementioned specifications is that, when subjected to conditions wherein the temperature of the mixture containing the composition and liquid prior to whipping is below about 50F. (C.) and in some cases below about 60F. (15.6C.), the resulting whipped product does not possess an acceptable overrun and viscosity or the composition may even fail to whip. These conditions may arise from the low temperature of the powdered composition itself, of the milk or water which is used to make up the topping, of the mixing bowl, or of the beater or other whisking implement, or combinations of any of these. When a prior art powder has been subjected to very cold conditions, e.g., around 32F. (0C.), it requires to be heated to above 70F. (21.lC.) before it recovers its whipping properties. Failure of products of this type to whip satisfactorily can and does occur during winter, probably due to a combination of the low temperatures of the powder and milk.

SUMMARY OF THE INVENTION It has now been found that whippable compositions having improved low temperature performance with out any impairment of their-organoleptic and performance characteristics may be obtained by the utilization, as the emulsifier component, of a particular mixture :of at least two emulsifiers which are designated herein as the primary emulsifier and the secondary emulsifier and wherein the primary emulsifier is a lactylated glycerol ester, and the secondary emulsifier comprises a partial or complete ester of a common food acid and a mono-arid/or diglyceride of a saturated or unsaturated fat forming C -C fatty acid. The preferred secondary emulsifier being an acetylated monoglyceride. The low temperature tolerance exhibited by the combination of the primary and secondary emulsifier described above is not exhibited by either the primary or secondary emulsifier when used independently in topping compositions, but appears to be dependent on some synergistic effect of these two emulsifiers in the proportions specified.

In accordance with the present invention there is provided a powdered, free-flowing, whippable composition having improved low temperature tolerance in the form of a dried emulsion containing fat, protein and carbolydrate and which includes, as a primary emulsifier, a lactylated glycerol ester and, as a secondary emulsifier, a partial or complete ester of a common food acid, as hereinafter defined, and a mono-and/or diglyceride of a saturated or unsaturated fat-forming C -C fatty acid, the primary emulsifier and secondary emulsifier being present in a total amount of up to 20 percent by weight of the dry solids and in a ratio from 5:1 to 1:1.

DESCRIPTION OF THE PREFERRED EMBODIMENT The lactylated glycerol ester used as the primary emulsifier in the composition of the present invention is a partial or complete ester of lactic acid and a monoor diglyceride of a saturated or unsaturated fat-forming C, -C fatty acid. One of the preferred primary emulsifiers is a glycerol lactopalmitate (GLP) which has been refined after esterification so that it comprises 92 percent by weight or more of the mixture of glycerol monopalmitate, glycerol di-palmitate, mono-lactylated glycerol mono-palmitate, mono-lactylated glycerol dipalmitate, di-lactylated glycerol mono-palmitate and tri-lactylated glycerol mono-palmitate, and less than 8 percent of homologous esters of stearic acid. Examples of glycerol lactopalmitate emulsifiers are those sold under the Trade name, Whippidan GLP419 and Whippidan GLP911 manufactured by Grinstedvaerket, Denmark and which conform to the following specification:

Acid value 2 3 Saponification value about 260 Iodine value 1.5 max.

Lactic acid content 13-15 percent Water soluble material nil Composition by weight of fatty acids:

C 2 percent max.

C 2 percent max.

C 93 percent min.

C 5 percent max.

The difference between GLP 419 and GLP 91-1 is that GLP 911 has a higher content of diglycerides and lactylated diglycerides than GLP 419, and GLP 419 has a higher content of lactylated mono-glycerides than GLP 911.

The common food acid used in the secondary emulsifier is defined so as to include acetic, citric, tartaric, malic or fumaric acid. Representative examples of the secondary emulsifier are the acetic, citric, tartaric or diacetyl tartaric acid esters of a mono-and/or di-glyceride, such as glyceryl monost'earate (GMS).

Preferred secondary emulsifiers are acetylated monoglycerides (AMG) such as those sold under the Trade Names of Myvacet (Eastman Kodak), Acetoglyceride H (Wilson-Martin) and Cetodan (Grindstedvaerket). Atypical specification range for AMG is given below:

EXAMPLE 4 Samples of spray dried topping were prepared according to the following formulations.

Composition E Composition F 50g of powder from each of the samples was added to 150 ml. of milk and the mixture whipped for 4 minutes. The tests were carried out under varying temperature conditions by the method previously described in Example 1.

For comparative purposes compositions A and D were also included in this series of tests. The results obtained are illustrated in FIG. 1 which is a graph of the Brookfield viscosity against whip temperature for Compositions A, E and F and comparative prior art Composition D. The graph clearly shows the improved low temperature performance of the composition of the invention over the prior art composition.
